To all whom it may concern:

Be it known that we, Trmononn A. CHEL- soN and HARRY J. BnNnnio'r, both citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Book-Marker, of which the following is a specification.

rlhis invention relates to a book marker adapted to be inserted in a book for enabling the reader to quickly turn to various parts of the book and one of the main objects of the invention is to so construct the device that the individual markers, when placed in position in the book, will not become disarranged, but will remain securely in place even though roughly handled. By reason of the firm location of the individual markers, it is possible to open t-he book at the desired place by simply taking hold of the projecting end of the marker and lifting those leaves above the marker and turn them over without having to touch the leaves.

A further object is to enable the markers to be readily attached or detached without perforating or marring the leaves or cover or any portion of the book.

A further object is to enable the marker to be employed with books of various thicknesses, the marker being self-adjusting.

Referring to the drawings: Figure 1 is a perspective view showing a book equipped with the marker. Fig. 2 is an elevation looking toward the front edge of the book with the covers partly open. Fig. B is a perspective of the retaining device. Fig. 4 is a plan view of the book as equipped with the marker with the top cover removed. Fig. 5 is a perspective view of one of the individual markers.

The device comprises a series of indi vidual markers adapted to be placed between the leaves of a book and a retaining device adapted to be placed around the body of leaves to engage the ends of the individual markers and retain them in position.

Each individual marker l comprises a main Ioar 2 with a lateral arm 3, formed preferably of a single piece of material, such, for example, as celluloid. The outer end of each arm 3 is provided with a numeral 4L which may serve to indicate the order in which the markers are to be used in opening the book. rlhe arms 3 are located at different points along the main bars 2,

so that when assembled in the book the arms 3 will all be visible, each one lying in a different plane. The individual marker is slipped in between the leaves of the book at the place that it is to mark with the main bar 2 lying close to the back of the book along the inner margin of the adjacent leaves, so that the reading matter is not obscured by the bar 2. The ends of the bar 2 project beyond the edges of the leaves 5 of the book, as clearly shown, to provide means for securing them in place, which means comprises the retaining device shown in Fig. 3. The retaining device comprises two bars 6 which may also be of Celluloid and which are connected at the ends by flexible bands or cords 7, each cord 7 being secured at each end at a perforation S, as by knotting the end of the cord inside of the perforation, the cords extending through perforations 9 at the ends of the bars G. After the markers are in position, the retaining device is slipped over the body of the leaves, so that each bar 6 lies between the cover of the book and the fly leaf or between a fly leaf and the main portion of the reading matter, so that the cords 7 will lie in front of the edges of the projecting ends of the bars 2. As the cords 7 are elastic they permit the bars 6 to spread apartto lit any width of the book and at the same time the cords clamp the bars 6 closely against the leaves, so that the bars 6 will not slip toward the front edge of the book, while the cords T act to lock the projecting ends of the bars 2 from slipping forward, thus the markers are all securely retained in position and yet may be readily removed when desired.

The ends of the arms 3 of the markers project from the front edge of the book a slight distance, so that the numbers 4 are visible and it is possible to grasp the arm 3 by the lingers to lift the leaves with the arm 3 as a support and turn the leaves open without requiring the fingers to be inserted between the leaves before lifting and turning them.

If it be desired to read certain portions of the book in sequential order the numerals on the respective marker arms 3 may be arranged in order and for convenience the numbers may run from the top toward the bottom of the book, thus the arm 3 bearing the numeral 1 will be located near the upper end of the bar 2; the arm 3 bearing the numeral 2 will be located slightly lower on its bar Q; the arm 3 bearing numeral 3 will be located still farther lower on its bar 2, and so on. Then the markers are arranged as indicated in F ig. l, the iirst portion of the book to be read is near the back of the book, the second portion to be read is near the front of the book, the third portion to be read is near the middle of the book, and the fourth portion to be read is substantially near the front part of the book, and so forth.

lV hat we claim is:

l. A book marker comprising' a series of individual markers comprising main bars with laterally extending arms, and means for detachably securing the individual markers in the book comprising a pair of bars between the covers of the book and body portion, and connections between the latter bars at both ends thereof, said connections extending across the front edges of said main bars to retain the latter but permit their easy withdrawal.

2. A book marker comprising a series of individual markers comprising main bars CIJ with laterally extending arms integral therewith, and means for detachably securing the individual markers in the book comprising a pair of bars between the covers of the book and body portion, and elastic connections between the latter bars at both ends thereof extending' across the main bars.

3. A book marker comprising a series of individual markers, each marker comprising a main bar with a laterally extending` arm, the ends of the main bars normally projecting beyond the ends of the leaves of the book, and a retaining device for securing the markers in position comprising a pair of bars with extensible connections at the ends thereof, the bars adapted to lie between the covers of the book and body portion of the book with said connections in front of the projecting ends of the main bars of the individual markers.

Ll. A book marker comprising a series of individual markers, the ends of each marker normally projecting beyond the ends of the leaves of the book, and a retaining device comjnising a pair of ba rs with yielding connections at each end, said bars adapted to lie between the covers and body of the book front edges of said with said yielding connections in front of the projecting ends of the markers.

In testimony whereof, we have hereunto set our hands at Los Angeles, California, this 27th day of August 1909.
